How to Audit User Access Without Disrupting Work
A former employee’s email account is still active. A team member can access the finance folder because they covered a holiday two years ago. A supplier has a shared login that nobody owns. These are ordinary oversights, but each one creates an avoidable route into business information.
Knowing how to audit user access gives you a clear picture of who can enter your systems, what they can see, and whether that access still makes sense. For small and mid-sized businesses, it is one of the most practical ways to reduce cyber risk without making everyday work harder.
Why user access needs regular attention
Most businesses do not deliberately give people too much access. It tends to happen over time. Staff change roles, departments take on new software, temporary permissions become permanent, and leavers are not removed from every platform. If IT support is split between several suppliers, it can be even harder to see the full picture.
This matters because a compromised account can be used to read sensitive files, send convincing fraudulent emails, alter payment details, or spread ransomware. Excess permissions also create operational problems. When too many people can change settings or delete data, simple mistakes can have wider consequences.
An access audit is not about assuming staff will do the wrong thing. It is about making sure permissions reflect the work people do now, rather than the work they used to do. It also provides useful evidence for insurers, clients, and sector requirements where you need to show that information is handled responsibly.
How to audit user access: start with a complete list
Begin by listing every system where someone can sign in or use sensitive information. Do not limit the review to laptops and company email. Most organisations now hold important data across cloud services, accounting software, customer relationship management systems, phone platforms, file-sharing tools, Wi-Fi, remote access, backup consoles, and line-of-business applications.
For each system, record the user’s name, job role, department, account type, level of access, and the person responsible for approving it. Include shared, service, administrator, guest, supplier, and former employee accounts. Shared accounts deserve particular attention because they remove accountability: if several people know one password, it is difficult to establish who made a change.
If this feels like a large task, start with the systems that would cause the greatest disruption or harm if misused. Email, Microsoft 365 or Google Workspace, cloud file storage, finance platforms, remote desktop access, and administrator accounts are usually sensible priorities.
The aim is not to create a spreadsheet that is forgotten next month. You need a simple register that can be updated whenever a starter joins, a person moves role, or someone leaves.
Check identity, ownership and account status
Every account should relate to a named person, a clearly defined business function, or an approved technical service. If you cannot identify the owner, treat the account as a risk until its purpose is confirmed.
Look for accounts belonging to former employees, agency staff, contractors, old suppliers, and duplicate users. Check whether inactive accounts are still licensed, still forwarding emails, or still able to connect remotely. Removing them may also reduce unnecessary software costs.
For legitimate service accounts, such as those used by backup software or a website integration, document what they do and who is accountable for them. These accounts often need elevated permissions, so they should not be ignored simply because no individual logs in with them every day.
Review permissions against the job being done
Once you know who has access, ask a straightforward question: does this person need this level of access to carry out their current role?
The principle is called least privilege. In plain terms, people should have enough access to do their job efficiently, but not wider access just in case it might be useful later. A receptionist may need to view a shared diary but not change user accounts. A finance colleague may need access to invoices but not unrestricted access to personnel files. A department manager may need to approve documents without becoming an administrator.
It depends on the size and structure of your business. In a small team, one person may reasonably cover several responsibilities. The important point is that this is a conscious decision, agreed by a manager, rather than a leftover permission.
Pay particular attention to administrator rights. Admin accounts can create users, reset passwords, install software, alter security settings, and access a wide range of data. Keep the number of people with these rights as low as practical, and consider separate administrator accounts for IT tasks rather than using an everyday email account with full privileges.
Confirm the controls around each account
Access is not just about whether an account exists. It is also about how well that account is protected. During the audit, check that multi-factor authentication is enabled wherever it is available, especially for email, cloud platforms, remote access, and finance systems.
Review password policies too, but avoid relying on password changes alone as your main protection. A strong, unique password and multi-factor authentication are more effective than forcing people to make predictable changes every few weeks. A password manager can help staff manage unique credentials without writing them down or reusing them.
Also check whether former devices still have access to company data. A personal mobile phone may retain business email after a staff member leaves, or an old laptop may still be signed into cloud storage. Your process should allow you to remove access remotely where appropriate.
Speak to managers before removing access
A good access audit should not disrupt the people keeping your business moving. Before changing permissions, share your findings with the relevant manager or system owner. They can confirm whether an unusual access right is genuinely needed for cover, a project, or a specialist responsibility.
This conversation prevents two common problems: removing access that is still essential, and leaving unnecessary access in place because nobody feels confident making a decision. Set a deadline for managers to respond, then record their approval or the action taken.
Where access is being reduced, explain the reason clearly. Staff are more likely to support security measures when they understand that the purpose is to protect clients, colleagues, and the business, not to make their job more difficult.
Put joiner, mover and leaver processes in writing
The best audit findings are quickly lost if access changes are handled informally. A straightforward joiner, mover and leaver process makes access control part of normal business operations.
For starters, agree what systems and permissions are needed before their first day. For role changes, ask the line manager to review both the access being added and the access that should be removed. For leavers, disable access promptly, collect company devices, remove remote connections, transfer ownership of files and mailboxes where necessary, and check that they are removed from third-party systems as well as your main directory.
Timing matters. In many cases, leaver access should end on the employee’s final working day, or earlier where there is a clear business reason. Your HR, management, and IT contacts should know exactly who authorises this and who completes it.
Decide how often to review access
There is no single review schedule that suits every organisation. A business handling financial data, health information, or client records may need quarterly checks. A smaller, lower-risk organisation might carry out a formal review every six months, with immediate checks whenever someone joins, changes role, or leaves.
You should also trigger a review after a security incident, office move, merger, major software rollout, or change of IT supplier. These are the moments when overlooked accounts and permissions are most likely to appear.
Keep a record of the date of each audit, the systems reviewed, the decisions made, and any actions outstanding. This creates accountability and means the next review starts from a reliable position rather than from scratch.
When external IT support is useful
Access audits can be difficult when systems have grown over years, there is no internal IT team, or nobody is certain which supplier manages what. An experienced IT partner can map your environment, identify high-risk permissions, help configure multi-factor authentication, and build a practical process around the way your team works.
For Derby and Derbyshire businesses, Alka IT Services can provide a clear view of user access as part of wider managed IT and cyber security support. The focus should always be on sensible improvements that reduce risk without adding unnecessary administration.
Start with your most critical systems this week. A short, well-organised review of who has access can prevent a small oversight from becoming a stressful and costly incident.
